javax.servlet.ServletException: Content-Type was '(null)'. Expected 'text/x-gwt-rpc'.

Hello,

We're using GWT 2.0, Spring 2.5.
On our production server we have sometime this error :

SEVERE: Exception while dispatching incoming RPC call
javax.servlet.ServletException: Content-Type was '(null)'. Expected
'text/x-gwt-rpc'.

I see this sometimes as well.

How can this be solved? Maybe putting a mime type in the web.xml ?

same here.

using GWT 2.4 and spring security (3.0.7), this appears during a login-logout-login scenarios.
